We all know that stomata are the tiny pores on the leaves which play a major role in the exchange of gases. The intake of carbon dioxide and the outgoing of oxygen both takes place through these pores. The respiration in leaves takes place through the tiny pores called stomata present on them. The exchange of gases occurs through these pores. The oxygen is transported to other cells of the plant by diffusion and in the same carbon dioxide is removed from the cells. In this way respiration takes place in leaves.

The digestive process begins in the mouth. Food is partly broken down by the process of chewing and by the chemical action of salivary enzymes (these enzymes are produced by the salivary glands and break down starches into smaller molecules).
After being chewed and swallowed, the food enters the esophagus. The esophagus is a long tube that runs from the mouth to the stomach. It uses rhythmic, wave-like muscle movements (called peristalsis) to force food from the throat into the stomach. This muscle movement gives us the ability to eat or drink even when we're upside-down.
The stomach is a large, sack-like organ that churns the food and bathes it in a very strong acid (gastric acid). Food in the stomach that is partly digested and mixed with stomach acids is called chyme.
After being in the stomach, food enters the duodenum, the first part of the small intestine. It then enters the jejunum and then the ileum (the final part of the small intestine). In the small intestine, bile (produced in the liver and stored in the gall bladder), pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food.
After passing through the small intestine, food passes into the large intestine. In the large intestine, some of the water and electrolytes (chemicals like sodium) are removed from the food. Many microbes (bacteria like Bacteroides, Lactobacillus acidophilus, Escherichia coli, and Klebsiella) in the large intestine help in the digestion process. The first part of the large intestine is called the cecum (the appendix is connected to the cecum). Food then travels upward in the ascending colon. The food travels across the abdomen in the transverse colon, goes back down the other side of the body in the descending colon, and then through the sigmoid colon.
Solid waste is then stored in the rectum until it is excreted via the ****.

The civil code of 1804 also known as the Napoleonic Code was enacted on March 21, 1804. It was one of the most important code of those times because institutionalised equalilty under law i.e. it ruled out privileges to people that were based on birth, allowed freedom of religion, and stated that only the most qualified would be entitled to government jobs.

Tricuspid valve: This valve opens to allow the blood to flow from the right atrium to the right ventricle. This valve is present in the junction of the right atrium and right ventricle.
Bicuspid valve: This is also known as the mitral valve. This valve is present in the left atrium. This valve opens to allow the blood to flow from the left atrium to the left ventricle.

In human beings, the blood goes through the heart twice during each cycle i.e. the blood passes through the human heart two times to supply once to the whole body. So, it is called Double Circulation of blood.
The double circulation of blood includes:
(i) Systematic Circulation
(ii) Pulmonary Circulation
Systematic Circulation: It supplies oxygenated blood from left auricle to left ventricle, thereby pumped to various body parts. The deoxygenated blood is collected from the various body organs by the veins to pour into vena cava and finally into the right atrium (auricle). Right atrium transfers the blood into the right ventricle.
Pulmonary Circulation: The deoxygenated blood is pumped by the right ventricle into the lungs for oxygenation. The oxygenated blood is brought back to left atrium (auricle) of the human heart. From left atrium, the oxygenated blood is pushed into the left ventricle. The left ventricle pumps oxygenated blood into aorta for systematic circulation.
It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature.

Different kind of organisms obtain thier food in different ways.
The process of obtaining food is called nutrition. Nutrition is of two types namely 1) HETEROTROPHIC And 2) AUTOTROPHIC.
Heterotrophic nutrition : It means organisms depend on other animals for thier survival.
All animals and non green plants are heterotophs.
Autotrophic nutrition : It means that the organisms make thier own food by using sunlight. All plants and photosynthetic bacteria are autotrophs.
